AS11982 SHWISP

SHWISP is Sandhills Wireless, LLC, a fixed-wireless broadband provider

based at 105 W 2nd Street in Valentine, Nebraska, serving the sparsely populated

Sandhills region of north-central Nebraska. The handle is literally the company's

domain, shwisp.net.

What it's used for

• Rural fixed-wireless internet access. The AS announces one prefix, 162.221.132.0/22 — 1,024 addresses — registered in ARIN to Sandhills Wireless itself. One aggregate, one registrant, one RIR: an entirely first-party inventory.
• A /22 is the whole network. That is a realistic subscriber pool for a WISP covering a handful of ZIP codes in one of the emptiest parts of the United States, where the customer count is measured in hundreds rather than thousands.
• Reverse DNS on one sampled address resolves to www.shwisp.net, the company's own site, so the operator plainly uses the space itself.

Notable

• A single observed neighbour. WISPs in this position typically buy one transit circuit and hold portable address space so they can change providers without renumbering their customers — that, rather than resilience, is usually why a network this small runs BGP at all.
• Another sampled address wears an echeloninternet.com hostname, a name not obviously Sandhills'. Reverse DNS shows what space carries, never who holds it, and a single PTR is far too little to build a story on — it is noted here only so a reader who sees it is not surprised by it.
